Here's How We Handle Your Repair

First, we diagnose the actual problem. No guessing, no assumptions. We test components systematically until we know exactly what’s causing your hot water issues.

Then we explain what we found and what it’ll take to fix it. You get clear information about your options – whether that’s a simple repair, component replacement, or if you’re better off with a new system.

Once you approve the work, we handle everything efficiently. We carry common parts on our trucks, so most repairs happen the same day. If we need to order something specific, we’ll get your system running temporarily while parts arrive.

After the repair, we test everything thoroughly and show you how your system is working. You’ll know what to watch for and when to call us for routine maintenance.

Everything Your Water Heater Needs

We handle both traditional tank water heaters and tankless systems. Gas, electric, hybrid – doesn’t matter. Our technicians carry diagnostic equipment for all major brands and models.

Emergency repairs get priority scheduling. When you have no hot water, we understand that’s not something you can wait a week to fix. Most emergency calls get same-day service, especially for our Comfort Club members.

We also handle full replacements when repair doesn’t make financial sense. If your system is old and likely to fail again soon, we’ll be honest about that. Sometimes spending money on a new, efficient unit saves you more headaches and money than patching an old one.

Age is the biggest factor. Most tank water heaters last 8-12 years, while tankless systems can go 15-20 years with proper maintenance. If your unit is approaching these ages and having problems, replacement often makes more sense than expensive repairs. Other signs pointing toward replacement include rusty water, multiple recent repairs, significantly higher energy bills, or not enough hot water even when the system seems to be working. We’ll always give you an honest assessment of whether repair or replacement is the better investment for your situation.
Sediment buildup is the biggest culprit, especially in older Weymouth homes with original plumbing. Minerals in the water settle at the bottom of tank systems, reducing efficiency and eventually causing heating elements or gas burners to fail. Thermostat failures are also common, particularly during winter months when systems work harder. In coastal areas like ours, humidity can affect electrical components over time. Tankless systems often have issues with scale buildup in heat exchangers, which is why regular maintenance matters so much for these units.
Most emergency calls get same-day service, especially if you call before 2 PM. Our technicians are based locally in the Weymouth area, so response times are typically 2-4 hours for true emergencies. Dempsey Comfort Club members get priority scheduling, which can mean faster response during busy periods. We define emergencies as complete loss of hot water, leaking that could cause property damage, or gas-related safety concerns. For non-emergency repairs, we usually schedule within 24-48 hours depending on current demand.
We service both tank and tankless systems regularly. Tankless units are becoming more popular in Weymouth, especially in homes where space is limited. These systems have different maintenance needs and failure patterns than traditional tanks. Common tankless issues include scale buildup, venting problems, and sensor failures. Our technicians carry specialized tools for flushing tankless systems and have experience with all major brands. Whether you have a Rinnai, Navien, Rheem, or other tankless brand, we can diagnose and repair the problem.
First, shut off the water supply to the unit – there should be a valve on the cold water line going into the top of the system. If it’s a gas unit, turn off the gas supply as well. Then shut off power to electric units at the circuit breaker. Don’t ignore small leaks thinking they’ll fix themselves – they always get worse and can cause significant water damage. Take photos of the leak location if possible, as this helps us prepare the right parts before arriving. Call us immediately for any leak, as this often indicates a serious problem that won’t wait for regular business hours.
Simple fixes like thermostat replacement typically run $200-400, while heating element replacement is usually $300-500. More complex repairs involving gas valves or control boards can range $400-800. The age and type of your system affects repair costs significantly. We always provide upfront estimates before starting work, so you know exactly what you’ll pay. Sometimes repair costs approach 50% of replacement cost, especially on older systems, which is when we’ll recommend replacement instead. Our diagnostic fee applies toward any repair work we perform, so you’re not paying extra just to find out what’s wrong.
